A square of plain tiling requires one bundle of laths andnails, one peck of tile-pins, and 3 hods of mortar.
The laths are sold in bundles of 3, 4, and 5 feet lengths ;a bundle of 3 feet contains 8 score; 4 feet, 6 score ; and 5feet, 5 score. The nails used are fourpenny ; and the num-bers required for a bundle of 5 feet and 6 feet laths, are 500and 600 respectively.
Calculation of Labour.
Digger. —The amount of digging which a man can per-form in a day depends so much on the nature of the soil onwhich he has to operate, that it is almost impossible to fix aConstant for this description of labour. The following datamay, however, serve as a slight guide:
In loose ground a man, will throw up about 10 cubic yardsper day, but in hard or gravelly soil, where hacking is neces-sary, from 3 to 5 cubic yards, according to the hardness ofthe ground, will be a fair day’s work.
Wheeling is estimated by the run of 20 yards. A gangof 3 men, 2 for filling and 1 for wheeling, will remove about30 yards per day to this distance; and the labour for re-moving earth may be calculated according to the distance,allowing 3 men to the first run, and an additional man forevery 20 yards of distance. [17-| cubic feet of clay weighsone ton. 18 cubic feet of common earth weighs one ton.]The following table, though far from complete, contains Con-stants for all the principal descriptions of bricklayer’s work.Concrete. —Labour in mixing, wheeling, throwing infrom a stage and puddling (when required to be done),
